Sienna Miller Loves Her Red Sunglasses

Three outfits, one day!

Sienna Miller sports her favorite shades — red Ray-Ban Wayfarers — while promoting her latest film Interview in NYC on Tuesday.

The British actress filmed Interview in NYC’s Tribeca back in April with Steve Buscemi, who pulled double duty as actor and director.

Sienna, 25, did a whole slew of press today from morning shows to The Late Show with David Letterman, which airs tonight @ 11:35PM ET/PT. The bright red minidress is by Valentino, bag from Balenciaga and sandals from Chanel. The babydoll gray dress is from her new line Twenty8Twelve.

Interview follows fading political journalist Pierre Peter (Buscemi) after a falling out with his editor. Somehow he is then forced to interview America’s most popular soap star Katya (Miller). The film opens in limited release on Friday, July 13.
